However, from another site, and man with Samsung box
Not sure if this helps anybody, but after reading through this thread, there seems to be two problems, the one related to recording and the one related to the EPG data.
I can't help with the recording one, and tbh don't actually care enough about it to even worry about it.
However, the EPG not downloading more than about 6hrs is a problem for me (as I do like to use reminders).
I never switch the box into standby, as i'm lazy like that. I don't like switching things off, as most things break when you switch them on, hence why I now have a HD box with 1 cable
It's a Samsung box with OS SYSF26.59.01 and EPG 40.0.14.1, the box is set to single feed mode, has only 1 cable and i don't configure any 'dummy' recordings.
Anyway, having tested switching the box into standby overnight, still leaves it with no EPG in the morning, so I would say under certain conditions that the standby methodology fails.
However I have found that if I choose Add Channel, and use the 11.778 V 27.5 and 2/3 and it finds 3 channels, either Add the channel called 8010 (Sky Promo, and it's a damn annoying 30 secs repeating advert) or the EPG background Music (quite nice) - Remember to store your choice, you can then view one of these channels, and then choose TV guide, and it will populate the bit you are looking at, thus allowing you to fill it up to 7 days in advance. The information then gets cached so it's visible when on normal channels.
The reason would apper to be that the full EPG is transmitted on that transponder.
A tad clunky, but a bit of a workaround for me, at least until i can be bothered getting on the roof and swapping the dish and adding a second cable feed.
Extrapolating further, switching off completely at night when outside the main footprint may also give rise to EPG loss even if the box is configured in single tuner mode.
